Will enterprises increasingly move away from using external vendor engineers to build their internal AI?
Gartner projects that 70% of enterprises will abandon vendor-deployed agentic AI solutions by 2028. This shift follows widespread struggles with high costs and an inability to maintain vendor-built systems independently.
Why it matters
The forecast highlights a systemic failure where enterprises trade long-term control for immediate deployment, often finding their AI platforms locked into unsustainable consulting-heavy models. This trend is accelerated by market practices where firms rebrand standard services as premium agentic engineering.
Gartner predicts less than 20% of vendor-deployed agentic engagements will successfully transition custom needs into long-term product capabilities through 2028. This compares poorly against standard software development life cycles where internal ownership is the baseline expectation.
The players
Gartner
A global research and advisory firm specializing in providing insights on technology trends and enterprise software strategy.
The details
Vendor-deployed engineering (FDE) involves external experts building and deploying solutions directly within a customer's environment. The process typically fails due to structural misalignment during delivery or exit, rather than initial technical limitations. Providers often engage in 'FDE washing,' where standard professional service hours are marketed as high-end agentic engineering to justify premium billing.
Timeline
By 2028, 70% of enterprises are expected to have abandoned their FDE-built agentic AI systems.
The Tech Race
This forecast marks a significant departure from the current industry push toward rapid, vendor-assisted AI integration. It positions the current wave of agentic AI deployments as a potential repeat of historically inefficient IT consulting cycles rather than a sustainable technical evolution.
Enterprises currently relying on third-party engineers must now establish rigorous exit plans and integrate those engineers with internal domain experts to avoid future technical isolation. Companies should audit their current AI vendor contracts to distinguish genuine agentic deployments from standard professional consulting services.
The takeaway
The trajectory suggests that long-term AI success will depend on internal ownership rather than external dependence. Industry leaders should watch for the 2028 milestone as the ultimate test of whether current vendor-heavy deployment models can evolve into sustainable internal infrastructure.
